©　Smithers　Information　Ltd.,　2016.Electron　beam　(E-Beam)　curing　technology　has　become　increasingly　applied　in　modern　composite　manufacturing　industry.　Comparing　to　conventional　thermal　curing,　E-Beam　curing　provides　an　efficient　solution　to　fabricate　integrated　composite　structures　of　a　wide　range　of　dimensions　with　a　minimal　consumption　of　energy.　Currently,　the　majority　of　E-Beam　curing　systems　use　high-energy　E-Beams.　However,　high　construction　cost,　high　radiation,　and　low　operational　flexibility　hinder　the　further　expansion　of　applications　of　this　technique.　In　this　study,　a　prototype　of　novel　dual-emitter　low-energy　E-Beam　curing　system　was　built,　which　was　energy　efficient　and　radiation　safe.　The　minimum　E-Beam　energy　that　could　satisfy　the　stepwise　curing　of　carbon　fiber/epoxy　composites　was　investigated　through　detailed　analysis　of　effects　of　the　irradiation　dose,　the　post　cure　temperature,　and　roller　materials　on　the　inter-laminar　shear　strength　(ILSS)　with　microstructure　characteristics.　The　results　indicate　that　carbon　fiber/epoxy　(CF/EP)　composites　can　be　adequately　cured　by　150　keV　E-Beams　using　our　system,　with　an　optimal　irradiation　dose　which　could　enhance　the　ILSS　as　largely　as　44.6　%　(from　34.2　MPa　to　61.7　MPa).　It　was　also　observed　that　laminates　irradiated　by　50　kGy　and　post-cured　at　180　°C　would　reach　the　optimized　ILSS　of　64.7　MPa.　An　anti-sticking　silicon　rubber　with　low　surface　energy　could　effectively　reduce　interlayer　defects,　resulting　in　higher　ILSS.
